Page 4: Hardware Setup
Hardware setup This code example has been developed for the board KIT_AURIX_TC297_TFT_BC-Step. The two pins P02.0 and P02.1 have to be connected to each other. Output Input 2019-10-17 Copyright © Infineon Technologies AG 2019. All rights reserved. - Page 5 Select the condition to generate an interrupt with the function IfxScuEru_setInterruptGatingPattern() – Configure and enable the service request with the functions IfxSrc_init() and IfxSrc_enable() › The functions above are provided by the iLLD headers IfxScuEru.h and IfxSrc.h. 2019-10-17 Copyright © Infineon Technologies AG 2019.
